This invention relates to an ice pick.

In delivering ice by trucks, wagons, etc., it has been found by actualexperience that the ice changes in hardness, as time passes, hence forreatest satisfaction in delivery, a peculiar pick is needed for use incutting the ice, under changing conditions.

Therefore, .an object of this invention is the construction of a simpleand efiicient ice pick, which can be used with the greatest satisfactionunder the changing conditions of the conveyed ice.

Another object of the invention is the construction of an ice pick whichhas as unitary parts thereof a plurality of blades with points ofvarying sharpness.

A still further object of the invention is to provide a handle With anovel detachable head or plug, for supporting efficiently each bladeupon the handle, as the operator requires.

This ice pick is an improvement upon the device disclosed in my priorUnited States Patent No. 1,956,875, issued May 1, 1934.

With the foregoing and other objects in view, my invention comprisescertain novel constructions, combinations and arrangements of parts aswill be hereinafter fully described, illustrated in theaccompanyingdrawing, and more particularly pointed out in the appended claims.

In the drawing:

Figure l is a view partly in elevation and partly in section of thehandle and head or plug of an ice pick constructed in accordance withthe present invention, showing one of the blades carried by the head.

Figure 2 is a view in elevation of the head with a blade having thesharpest point for cutting hard ice.

Figure 3 is a view in elevation of the head with a blade of a bluntercharacter, or less sharp point, than that shown in Fig. 2, for use onthe ice as it becomes more tempered or softer, while Figure 4 is asimilar view of the bluntest or less sharpened point blade for use onthe ice as it becomes more soft, or honey-combed or white ice.

Referring to the drawing by numerals, I designates a handle which isprovided at its outer end with a cylindrical socket 2. Around the outerend is preferably a metal band 3 for strengthening the socketed end.

The improved and novel head or plug 4 comprises the annular grip 5integral at one side with the long primary cone 6, and at its oppositeside with the short auxiliary cone 1. In the head 4 is a suitable socket8 into which extends the inner end of the blade; in Fig. 1 I havepreferably shown a blade 9 which is also illustrated in Fig. 2. Thisblade 9 is what might be called a long slim blade, being of the greatestsharpness for cutting hard ice, as the ice is first handled in the plantor delivered to the trucks and wagons. When the head is assembled withthe handle I (Fig. 1) the long primary cone extends into the cylindricalsocket producing a bearing In at the outer end of the socket 2, on thecone 6, whereby, as the operator cuts the ice the blade is permitted toslightly move, in different directions, as illustrated by the dottedlines A and B of Fig. 1 which produces an effect like a universal joint;this little give", in any direction, reduces the breakage of blades to aminimum, whereby their usefulness is greatly increased; this has beenfound to be true from extensive experience with a full sized workingdevice, constructed in accordance with this invention. Of course, itwill be understood that with each stroke of the pick, the head is wedgedin tightly, but by reason of its small bearing II), it is allowed togive for producing the action clearly indicated by dotted lines A and B.

I have found that when the ice is fresh and hard right out of the plant,it requires a long slim blade (Figs. 1 and 2) to cut it or break it.Then after it has been hauled for a while outside, the ice becomestempered or a little softer and requires a blunter blade ll (Fig. 3), assuch blade goes into the ice deeper. Then as the ice gets softer orhoney-combed it requires a still more blunt blade I2; in other words, itrequires three styles of blade to satisfactorily deliver a big load ofice. With the handle I and the three blades 9, H and I2, of differentsharpness or taper, one can get along without breaking the pick blades,because what breaks so many points of blades is this: the ice softens asit is hauled around and the blades sheer off to one side and the steelis so hard that it will not bend, hence the blade or blades break; byusing my improved and novel head the primary cone gives the properassembled result as well as the universal movement shown by dottedlines, for maximum efficiency.

The operator can quickly make changes of blades, owing to thedetachability of the novel head, from the handle, and by reason of thenovel and peculiar structure of the entire device, it has been foundfrom extensive experiment and practical use that a very efficient icepick has been invented.

While I have described the preferred embodiment of my invention andillustrated the same in the accompanying drawing, certain minor changesor alterations may appear to one skilled in the art to which thisinvention relates during the extensive manufacture of the same, and I,therefore, reserve the right to make such changes or alterations asshall fairly fall within the scope of the appended claims.

What I claim is:

1. As a new article of manufacture an ice pick comprising a handleprovided at one end with a cylindrical socket, a head comprising anannular grip and an integral long primary cone extending from one sideof said grip, an integral auxiliary cone extending from the other sideof said grip, said long primary cone extending into said cylindricalsocket,said socketed portion of the handle forming a bearing on saidprimary cone at the outer end only of said socket, whereby the primarycone is permitted to have a slight universal movement in said socket,and a blade extending into said head, substantially as shown anddescribed.

2. As a new article of manufacture, an ice pick comprising a handleprovided with a cylindrical socket, a head provided with a cone, saidcone extending into said cylindrical socket and normally only bearingagainst the outer end of said socket, and a blade mounted on said head.

3. As a new article of manufacture, the combination of a handle providedwith a cylindrical socket, a series of blades of different sharpness, a.similarly constructed head on each blade, said head provided with a longcone, and said cone adapted to be positioned in said cylindrical socket,whereby a small bearing is produced, allowing of slight varyingmovements of the head on the handle during the operation of the device.
